The intervention that is designed specifically to open narrowed or blocked peripheral arteries is known as a percutaneous intervention. This minimally invasive procedure typically involves the use of techniques such as angioplasty and the placement of stents. In angioplasty, a small balloon is inflated at the site of the blockage, which expands the artery and restores blood flow. If necessary, a stent may be deployed to keep the artery open over the long term.

Other options involve different processes that are not directly aimed at addressing peripheral artery blockages. For example, endovascular graft procedures focus on repairing larger vascular structures rather than simply opening blockages. Transcutaneous pacing is related to temporary cardiac pacing and has no applicability in peripheral artery interventions. Ablation therapy targets specific areas of abnormal tissue in the heart, often used in the treatment of arrhythmias, but does not open blocked arteries. Thus, the nature and goals of percutaneous intervention make it the appropriate choice for treating narrowed or blocked peripheral arteries.
